COIN-CHANGING MACHINE.

Application filed January 11, 1923. Serial No. 612,081.

The invention relates to improvements in a coin changing machlne, which may be regulated to give an equal value in coins of any desired denominations in exchange for any coin inserted into the machine through its correct slot. Coins inserted to be changed may themselves be given in change for coins of higher denominations.

l/Vith these and other advantages which will be set forth, the machine is easily constructed, simple in operation, cannot be cheated and is readily adapted to meet varying requirements in regard to the amount and denominations of change to be given or deducted for any coin inserted inits correct slot, as will be fully'set forth.

In the drawings,

Fig.1 is a longitudinal section view of the machine;

Fig. 2 is a vertical section through the machine,

Fig. 3 is a plan view of the coin slots;

Fig. 4 is a plan view of the sliding plates with cushioned slots;

Fig. 5 is a plan view of the coin maga-- zines and means of obtaining change;

Fig. 6 is a variation of Fig. 4 showing the coin plates separated;

Fig. 7 is a variation of Fig. 1, showing a machine designed to operate with fewer denominations of coins, and in which several coin magazines. includingthe extra nickel magazine, have been omitted In the preferred form of the invention. 1 represents the general body of the machine, which may be of any desired shape. or size, having doors 2 on opposite sides opening on hinges 3. There are separate coin slots 4:

through the top of the machine, as shown in Fig. 3, for inserting each size coin whic'h is to be changed. Each of sald slots is large enough for the coin for which it 18 made,

to 'go through, but not large enough for colns of greater s1ze to pass into the ma-- chine. Said coin insertion slots are arranged in order, according to the denomination of the coins to be changed, beginnng with the largest, the various denominations of the said coin insertion slots, alternatihg in two parallel rows. Under each of the said insertion coin slots there is a coin guide 5, shown in Fig. 1, which will direct any coin admitted through any of the insertion slots to a second -coin, slot, 6 on a plate 8; each of the said second coin slots is slightly wider at its top than at its bottom. A spring or cushion regulates the size of the COlIl which can pass through a slot. Each of the said second coin slots 6 is on a separate plate 8. limb of said plates 8 is disposed end to end between two grooved supports 9, in which they are slidable in the same direction and in the same plane. Said plates are arranged in order from the platehaving the cushion slot for the highest denomination coin to the plate having the lowest denomination coin in its cushion slot.

A coiled spring 10 acting on the lowest denomination coin carrying plate will bring all the said cushion slots back to a position directly under a corresponding denomination coin insertion slot, when the force which has moved any or all of the said plates out of said position has been removed.

The highest denomination coin carrying plate will come to rest in that position against its stop 11, and each of the said plates will then hold the next plate to it in thesame relative position, with its coin slot directly under the corresponding insertion slot. A. coin pusher 12 slides between two cuts 13 in the cover of the machine on its supports 14 and having its handle 15 extending above the machine, and its base 16 resting on the grooved supports 9 on which the said base slides. One end of a coiled spring 17 is attached to the said pusher at 16 and the other end attached to the machine at 19, said spring going over a roller 36. Nearone end of each of the said guides 5 is a flat piece of metal 20, fastened under the cover of the machine in such a way that a coincarri'ed in a cushion slot 6 and coming into contact with the said piece of metal 20 will swing it away from the said guide 5, but the said guide 5 will keep the said piece of metal from swinging in the other direction when a coin comes against it from the opposite side.

There is one coin pressing device 21 for each cushion com slot 6, each of said 'devices 21 being attached to the cover of the machine on'its under side insuch a way that any coin carried in a cushion slot a sufiicient distance by the handle 12 will come in contact with a presser 21 and the said cushion or spring 7 will then allow the said coin to be pushed through its slot 6.

Directly under each of the two grooved supports 9-there is a row of coin magazines 22 attached to supporting rods 23 as shown in Figs. 1 and 2. One row of said magazines comprises coins of fifty, nickel and dime denominations in the order named, the said nickel magazine having its upper section 37 extending out of the machine for inserting coins in, and being different from the others as will be stated below and re ferred to as the extra nickel magazine. The other row of magazines comprise one magazine for twenty-five cent coins, and one magazine for coins of five cent denomination as shown in Fig. 5. At one end of each of said rows, which are parallel, is another row of five magazines 22, Fig. 4, of penny denominations having a cover as shown-in Fig. 3. Each of said magazines 22 except those for the pennies, the highest denomination cointhe dollar-and the extra nickel, has one end of a coin chute 24 fastened to it. The other end of said coin chute is adjacent to one end of each cushion slot for coins of the same denomination as the magazine to which the other end of said chute leads. Said chutes 24 are so situated that all coins are forced through the said cushion slots by the pressers 21, and will slide down the said chutes 24 to their respective coin magazines.

WVhen any of the said magazines 22 are full of coins the overflow will be carried down said chutes 24 and will slide overthe top of the coins in the said magazines 22, and will then fall through the opening 46, and into one of the drawers 31, 32, located on each sideof the machine. Each of said drawers is opened by means of its handle 33. vAs the dollar coin is not given in change it is carried down the chute 44 by means of gravity through the opening 46 into 31 having a lock 39 and any other coin may likewise go directly into a coin drawer instead of its magazine by adjusting its coin chute accordingly. All coins falling through coin slots before they have been moved a sufiicient dis tance to come in contact with a presser will,

on falling through their respective slots, fall onto a hell 25 situated directly under each of said coin slots, and then slide off the hell and fall through the opening between the plates 28 shown in Fig. 5, and then slide down the incline 26 and out of the machine at 27. Sliding on its support just above the bottom of each coin magazine and of the approximate thickness equal to the coin in its respective magazine is a plate 28 having a circular outline aperture 29 therein, corresponding to the size of the bore of the magazin'e under which the said plate is located. Said plates are mounted to slide just over the supporting partition 34 of their respective coin magazines, and produce one coin from its magazine. Each plate 8 has a cush ioned slot for coins of different denominations, the slot in each plate being of different size, and each.has a separate rod 30 riveted to it, the other end of the said rod 30 being releasably attached to the plate 28 wnlcn slides under a coin magazine of one denomination lower. The said rods 30 extend and operate in an open space betweenthe two parallel rows of coin magazines, and coins too small for any slot drop through said open space onto the incline plane 26, and then slide out of the machine through the exit 27. The two plates 8 and 28 which are fastened to the'ends of each rod 30, must move together unless the plate 28, which is under a coin magazine is disconnected from its rod, in which case said plate :28 will not be moved by the said rod 30, and one coin of the denomination ordinarily obtained when said plate is moved, will be deducted in giving change. The plate having the dollar cushion slot is connected to the plate under the fifty -cent magazine, likewise the plate with the fifty-cent cushioned slot is connected to the plate under the twenty-five cent .magazine. The plate carrying the twentyunderv the said extra nickel magazine and is so constructed that when moved a suflicient distance, both a dime and a nickel will be obtained from their respective magazines. The plate carrying the dime cushioned slot is likewise fastened to and controlsthe plate under the nickel magazine, and the plate carrying the nickel cushioned slot is connected to a plate which slides under all the penny magazines and is so constructed that it will obtain one penny from each magazine. Unless one or more of said change obtaining plates 28 is disconnected, from a rod 30 as stated above, coins inserted will produce the following change when the machine is operated. A nickel inserted through its correct slot will produce five pennies. A dime inserted will produce a nickel and live pennies; a quarter inserted will produce the extra nickel, a dime, theordinary nickel and five pennies. A fifty-cent piece will produce in change a quarter, the extra nickel, a dime, the ordinary nickel and five pennies. And a dollar coin inserted will produce fifty-cents, a quarter, the extra nickel, a dime, the ordinary nickel and five pennies. To keep coins out of any insertion coin slot, a set screw 35 is placed through the guide 5 under the said insert-ion slot, as shown in Fig.

llll) llO 1. One end of a pivoted plate 20 is pivoted changed is dropped into the correctinsertion slot through the cover of the machine;

ing each successive plate not having a coin' in its cushioned slot until it comes in con tact with a coin in a cushioned slot. The plate having the saidcoin in its cushioned slot, andall the plates with cushioned slots for coins of smaller denomination, will be moved in the same direction, but the plates having cushioned slots for larger denomination coins will not be moved. Each of the said plates under the coin magazines which are connected by means of the rods 30 to any of the plateslmoved by base 16 of the handle 15 coming in contact with the said coin in a cushioned slot will themselves be moved a suflicient distance for each to produce one com from its respective magazine.

The said coin will be carried so that it will raise the pivoted plate 20 to a sufficient height to allow the coin to pass under it,

and the coin will then eventually come in contact with the depresser 21 at a point where it is directly over its coin chute 24 and said coin will then be forced through its cushioned slot by its said depresser 21 and fall into its chute '24 and be carried to its respective coin magazine, where the said com wlll eventually begiven as part change for a coin of lngher denominatlon.

Any coin produced as change from its maga zine will be carried down the inclined plane 26 and out of the exit 27. When the said coin has been removed from its cushioned slot the spring 10 will bring the various moved parts of the machine back to their.

original position, withthe exception of the handle, which on being released will be brought back to its original position by the spring 17, and the machine will be ready for operation again. By disconnecting any number of plates 28 under the coin magazines from the rods 30- to which each is connected by means of a screw a-regulated amount of change may be deducted each time the machine is operated. 'Assuming it is desired to deduct six cents from any coin I inserted to be changed, it is only necessary to empty one of the penny magazines and the nickel magazine of their respective coins. In this case the spring or cushion under the slot in the nickel carrying'plate would be adjusted so that a nickel would fall freely through the slot -without operating the machine, as the value to be deducted in this case is more than the value of a nickel. The nickel would slide down the inclined plane 26 and to the exit 27. Any amount of change may be deducted in like manner or the same:.etfect may be accomplished by emptying all the coins from magazines corresponding to the change desired to be deducted.

Only coins of correct size for each slot will have any eifect on the machine as the others will either not be admitted or will fall through and be returned to its owner.

Fig. 6 shows how shorter cushioned coin slot plates may be substituted for the longer ones, each of said plates having a separate spring 42 which normally holds it against a set screw 41 inserted through one of the groove supports, This is accomplished by having. one end of the spring 42 fastened to the set screw 41 and the other endfastened to the sliding plate at 43. In this way the said plates are separated, and each may be moved in its grooved supports without moving any other cushioned slot plates, and each of said plates can only move the change obtaining plate 28 to which it is connected. By inserting a shorter plate or bumper between each of the said cushioned slot plates and removing the set screws in the grooved supports, and adjusting one or more-of the springs, the said plates will operate as in Fig. 4..

In Fig. 7 all the coin magazines are in a single row, and several have been eliminated including the extra nickel and four of the penny magazines. The plate under the penny magazine is made' thick enough to obtain five pennies each time it is moved. A chute 45 may direct the largest denomination coin'to acoin drawer located on either side of the machine When this principle of obtaining more than. one com from each magazine is applied with the shorter plates shown in Fig. 6, it is possibleto obtain the highest denomination of chan e for each coin insertedin the machine' The number of times the machine is used maybe shown loo by'having the piece of metal 34 operate a weight. I' do not limit myselfto any special number, height, denominations or arrange- 'ments of the coin magazines. Neither do I limit myself to any special method of obtaining change from the said magazines.
